Redmine not start, log says ActiveRecord::AdapterNotSpecified, some other
stranges

FreeBSD 9.2 Apache 2.4 + Passenger Trying to start Redmine 2.3.2
Error:
/usr/local/lib/ruby/gems/1.9/gems/activerecord-3.2.13/lib/active_record/connection_adapters/abstract/connection_specification.rb:47:in
`resolve_hash_connection': database configuration does not specify adapter
(ActiveRecord::AdapterNotSpecified)
I found that if I change adapter from "adapter: mysql2" to
"adapter:mysql2" (remove space after ":" ) then this error gone, however
then I have another error:
/usr/local/lib/ruby/gems/1.9/gems/bundler-1.3.5/lib/bundler/dsl.rb:33:in
`rescue in eval_gemfile': Gemfile syntax error: (Bundler::GemfileError)
So I have to make it work when "adapter: mysql2" is configured, so I have
to solve ActiveRecord::AdapterNotSpecified error problem somehow else, not
by removing space there.
Any ideas?
